n+d+q=46

n=q+11

10d=25q-100

From the 3rd -->d=2.5q-10

The 1st: (q+11)+(2.5q-10)+q=46

q=10

n=21

d=15

The number of nickels she has is 14 less than twice the number of pennies; the number of dimes she has is 22 less than three times the number of pennies. How many coins of each kind does she have?

n=2p-14

d=3p-22

p+(2p-14)+(3p-22)=120

6p-36=120

6p=156

p=26

n=2(26)-14

n=52-14

n=38

d=3(26)-22

d=78-22
